Description from the seller
EXCEPTIONAL OPAL - MEXICO
Here is a rare and captivating piece, a true natural work shaped in the volcanic depths of Mexico. This fire opal, cut and polished into a cabochon, reveals a mosaic of translucent fragments in warm tones: amber, honey, caramel. Some areas show internal flashes, almost vitreous, while a rougher core, with a mineral texture, evokes the earthly origin of this spectacular gem.
The Mexican fire opal is an emblematic stone of the high volcanic plateaus of the state of Jalisco. Valued since pre-Columbian times, it has gone through centuries without losing any of its power to fascinate. Unlike the noble opal that plays with all colors, the fire opal captivates with its internal light, often orange, sometimes golden, and its almost solar appearance.
Technical characteristics:
Weight: 102.45 carats
Dimensions: 50.1 mm x 28.6 mm x 10.4 mm
Origin: Mexico
Color: Shades of golden yellow, amber, and light brown
Shape: Cabochon polished on matrix, refined finish
Texture: Translucent zones mixed with a porous, contrasting matrix
Details:
Museum-grade format, rare for sale
Beautiful alternation between polished brilliance and raw material
Presence of a natural crystal heart, not reworked
Conclusion:
A unique and spectacular piece, a true testament to Mexico’s mineral wealth. Its generous size, warm palette, and hybrid character between gem and matrix make it a specimen worthy of the finest display cases in a collection or an elegant presentation.
An exceptional piece for its size and the sharpness of its fire, well highlighted by the contrast with the natural matrix.
We are passionate sellers and select each stone with the utmost care for its quality and authenticity.
